What is Java Language?

Java is one of the commanding general-purpose programming languages. We can develop various mobile and desktop applications and embedded systems using this Java programming language. If you count the number of benefits of Javed, the list Will Go On.

Sun Microsystem developed this popular Java programming language, but later on, Oracle acquired Java. The official statement of uses of Java programming language then you can find out that there are more than 3 billion + active users or active downloads of Java programming software, which sources the popularity of Java programming language.

Let’s start with some basic concepts of Java, which will help learn Java programming for beginners with some step-by-step tutorials and simple Java programs.

What is Core Java?

In learning Java programming language, it may be hard to understand the basic terms of Java: Core Java and Advanced Java. So before digging into the Java tutorial concept, little do you know about core Java and Advanced Java?

  • Core Java
  • Advanced Java

Core Java: Sun Microsystem uses the term Core Java. A basic version of Java refers to the collection of libraries rather than the programming language. It is a standalone Java application that covers various topics like the OOPS concept, operators, data types, wrapper classes, collection & and exception handling.

Advanced Java: Advanced Java is also one of the parts of the Java programming language. But you can even say that the adventure is everything beyond Core Java. Advance Java, mostly the API, is defined in Java Enterprise Edition (JEE), including servlet programming and web Services. It combines web and enterprise application development, following client and server architecture.
